Comparison of Commercial Multiphase Flow Simulators with Experimental and Field Databases

Abstract

Two commercial multiphase pipe flow simulators, OLGA ® 5.3 and LedaFlow ® , have been tested on laboratory and field data. Regarding the laboratory data, the results are comparable, however, two weak points have been identified: an overprediction of the liquid hold-up in stratified flow and a relative error up to 70% on the pressure-gradient in intermittent flow. Two field cases, one oil-dominated and the other gas-dominated, have been tested. The predictions show very good agreement with the available field measurements of pressure drop and temperature. In the gas-condensate case, similar turndown and liquid accumulation curves are obtained.
